sieve sender

[Erik Myllymaki]

I think this is not a Sieve problem but one that affects sieve.

When using a sieve redirect, the Sender of that mail gets set to
<cyrus at mail> and thus generates an error message about an invalid
sending address from SMTP servers other than our own.

I am unsure where in my config I should look to make that a FQDN instead
of just the imap servers hostname.

Any tips greatly appreciated.

Thanks.
